(ominous music) - Doc, my husband is just, he's not, he's not my husband.
It started last week.
We had such a wonderful night cooking up some proteins and then, you know, we had mitosis and it was all so perfect.
But then the next day, he started acting really strange.
He had this funny look around his mitochondria.
He's just, oh, it's horrible.
- I'm sorry, but I'm gonna have to ask you, well, a sensitive question.
- Ah, how to put this.
Has he been opening his membranes to anyone strange or new?
- (startled gasp) What?
No, of course not!
We are always very careful.
- Oh, okay, well tell me.
Who had he opened his membrane to around the time, well, you noticed the change?
- [Wife] Well, just the normal mail couriers with packages of proteins, minerals, and sugars.
- [Doc] And nothing suspicious?
No unusual packages delivered?
- Well, come to think of it.
There was one strange package with a fairly explicit piece of genetic code.
But when I asked my husband, he said they mail those out to everyone, not to worry.
- Oh, all right.
Did it look like this?
- Yes, that's it.
- [Wife] What?
- Well, that's a virus.
I'm afraid your husband has been invaded by what we call a virus.
(startled gasp) Once your husband opened up his membranes to accept that package, it spit out its own genes into him hijacking your husband's genetic instructions.
Clever creatures really.
- Are you say that my husband has become a virus?
- Oh no, not a virus, imagine, more a virus factory.
You see, these virus invaders don't bother to do any of the hard work that we cells do.
A virus hijacks a cell to make millions of copies of itself.
It's really amazing.
Well, of course, until the cell bursts and the virus spreads to more cells.
We need to check you to make sure you haven't been infected too.
Ma'am, are you okay?
- I'm fine.
All this is just a lot to take in.
